What's Missing?

Below are programs that are mostly done, but are either missing pieces of code, or there is a typo, or any other kind of error. Your task is to fix the program so it would compile.

1. Difficulty: Easy

//**CODE THAT IS MISSING WILL BE REPLACED BY "??"**
//There may be other errors that are not marked (ex: missing a semicolon)
 
 
import greenfoot.*;
 
//Turtle that runs in circles
 
public class CircleTurtle extends Turtle
{
    private ?? speed;
    private ?? turnRate;
    private ?? isClockwise;
 
    public CircleTurtle()
    {
        speed = 5;
        turnRate = 2;
        isClockwise = true;
        penDown();
    }
    public int getSpeed( //Find how fast the turtle is moving
    {
        ?? speed;
    }
    void isClockwise() //Makes the turtle switch directions
    {
        isClockwise = ??isClockwise
 
    public void act()
    {
        move(5);
        if(isClockwise)
            turn(2);
        ??
            turn( ?? 2);
    }
 
}
